Tig Welding Galvanized Steel

Tig Welding Galvanized Steel - The process of welding galvanized steel is an extremely hazardous job, as the zinc coating that is galvanized on the metal can be extremely poisonous when heated. 

Make sure you are taking the appropriate precautions to protect yourself by wearing an appropriate welding mask, a excellent welding respirator and gloves as well as an apron. 

Tig Welding Galvanized Steel

Make a ventilation system by using an extractor for fumes or a set of several fans, and try to remove all of the zinc-coated coating you are able to prior to starting to work. 

It is also necessary to use an arc welder since the MIG welder will not be able to join the galvanized steel. 

When welding, go in a circular motion over the opening or seam and then cover the entire area twice to join two surfaces.

Setting up a Safe Workspace

Make sure you have a welding mask, protective gloves for welding, a respirator and an apron.

Galvanized steel can be extremely harmful when you join it. 

It's coated with zinc-based coating, which can be extremely harmful to humans ingestion. 

You must take several steps to stay clear of the toxic fumes. 

Start by buying a good welding mask, heavy-duty respirator and a pair of welding gloves. 

Use a welding apron in order to prevent sparks from destroying or harming your clothes.

Find a respirator specifically designed to be used for welding metal. 

A typical dust mask or respirator is not suitable for welding.

Some welders suggest drinking glasses of milk, or taking calcium supplements prior welding galvanized steel.

The calcium supplement can reduce the fumes from zinc that you might be able to inhale accidentally.

Utilize a fume extractor, or place fans right near your welding location. 

If you're establishing your welding in an industrial or work location, put the fume extractor about 3 feet (0.61-0.91 meters) far from the location you're welding in order to take in the fumes right away as they're released. 

If you're a self-taught DIY who doesn't have access an extractor install at least a few fans by your left to blow the Zinc fumes away.

Try to go outside if you are able. 

If not open as many windows as you are able to. 

If windows aren't opening then find a different means to let air circulate through the room. 

Galvanized steel isn't able to be welded inside a closed space.

A fume extractor can be described as a type of vacuum with a heavy duty which collects the fumes before they're released. 

It's possible to hire the equipment from an building materials retailer or contractor if you do not have one.

The welder is grounded using the clamp on the clamp or the work surface. 

Certain welders must be grounded in order to stop the electrical currents that cause shocks to be able to stay away. 

If the welder has the clamp that is similar to jumper cables in a car or other vehicle, it must be grounded. 

The grips should be opened and let them go around the clamps made of metal to ground the item it self.

You could as well clamp an item metal directly, or even the work surface you're working on.

It is best to ground the object itself in case you're working outside.

It is not recommended to touch the object you're welding with your hands at all however, even if you do, the chances of getting electrocuted are small. 

This is another security measure you have to follow to ensure your safety when you're working.

Sanding and Securing Your Project

Remove the zinc coating around the location that you're welding. 

Wear your respirator, protective masks as well as gloves. 

Make use of a 220-grit sandpaper or a grinding machine at a lower setting to remove that zinc-coated coating. 

This helps in forming and maintaining a constant line, but isn't necessary in the case of an extremely thin coating of galvanized and making use of rods that are suitable. 

This will also improve chances of not being exposed to any toxic gasses.

If you're looking strip the smaller parts of your material such as galvanized bolts or strips, soak overnight in a cup vinegar.

As galvanized steel is welded, it releases toxic fumes into the steel, but grinding or sanding it doesn't.

Put the two pieces together or separate your repair. 

Place your two pieces of galvanized steel on the work surface and arrange them in the way that you would like they will set. 

It is not necessary to secure the pieces in place while you are welding. 

If you're welding a hole or tear it to close it put your workpiece on the work surface in such a way that the opening faces upwards.

If you're required to spread your pieces on the ground, make sure you're welding an uncombustible surface like concrete.

Make smaller pieces clamped using an iron clamp when you are able to.

If you're clamping two sheets or joints, and they're large enough to fit in the clamp, you can make use of a welding clamp to join them and create an ideal seam. 

Welding clamps are made of iron or clamps. 

For the welding clamp you need to place two pieces of metal between the two ends of the clamp. 

The frame should remain still as you move the dial at the end clockwise until the clamps are closed over the 2 pieces to keep them in place.

Welding clamps are commonly called C-clamps.

When you're working with clamps that weren't specifically advertised as welding clamps you could probably use any clamp made of steel. 

Plastic clamps aren't able to secure two objects to make welding.

Using the Welder

Utilize an arc welding machine to welding galvanized steel. 

An arc welder that is standard in design is the most efficient way to join galvanized iron. 

It is a flexible technique that makes use of alternating currents to produce an arc with high heat which melts the flux.

If you're able use outside, do so when working with an arc welding device. 

There are occasions when splatters occur caused by the spread of the weld.

If you're new to welding and have only room for one welding machine in your workshop, go for an Arc welder. 

It's the simplest welder to make use of, and is the one that the majority of people consider when they imagine welding.

Choose your welding rod according to the size that the material. 

It is possible to utilize a rod for welding in any size so you can use it in conjunction with your welding.

Remember that a rod that is larger will be able to provide more coverage than smaller rods. There are no specific or galvanized steel-specific equipment or materials you require. 

Utilize 6013, 7018, 6011 or 6010 welder rod. 

These are the most commonly used rods therefore they aren't difficult to find.

Begin at one end of the seam, if you're joining two pieces. 

If you're welding two sections of steel, begin at the edge of the seam, that they will meet. 

Start your welder by turning it off by placing the rod of welding about 1-2 inches (2.5-5.1 cm) away from the start of the seam. 

Then press either the switch or trigger until you let go of the flux.

Sparks will come out when you begin welding. 

Do not try to dodge them. 

Do your best to hold the rod in its place. 

You'll be fine wearing the appropriate safety equipment.

Move forward and backwards to apply the welding flux, and then heat it. 

The welding rod should be moved across the seam for about 2 inches (5.1-7.6 cm) at each pace. 

Then, move back across the area you have just welded, slightly slower than the forward movement.

After you've covered the surface twice, proceed to the next section of seam. 

Repeat this procedure throughout the gap in order to bond the two pieces together.

You should wait at least 15 minutes allow the welding flux to be able to settle before attempting to check the bonds. 

You can also smooth it out.

Weld around the edges of a split and work your way up. 

To join a tear or fracture in galvanized steel begin by putting your finger on the edge that the steel.

Begin by working slowly around the outside edge of the metal and move forward by about 2 inches (5.1-7.6 cm) before bringing the welding rod back to the area you've just covered. 

Repeat the process until you've made it all around the edges of the split or cut and then work your way towards the middle of the opening, and repeat the procedure. 

Continue this process until the whole hole is completely covered.

You can't glue a split or tear close if the gap at the center is larger than 1 inch (2.5 millimeters). 

The welding material simply cannot remain closed over the course of time.

Take 15 to 20 minutes to let the welding flux cool to ensure you are at a safe distance.

You can also grind the excess flux off and then paint the area If you wish.
