How To Fit Pipe For Welding

How To Fit Pipe For Welding - Pipe welding can be described as a complicated task that involves the joining of two metals that are curved. 

The process can be achieved by using a variety of welding methods such as the TIG method, MIG or arc weld. 

How To Fit Pipe For Welding

Heavy-duty and thick materials are commonly used for this procedure, and the nature of the welding process means that the ability to see and take precautions are essential to ensure complete penetration. 

It is essential to prepare early for every welding project.

Follow This Procedure for Fitting a Pipe

Here is a step-by-step guideline to connect two pipes prior to welding.

Install the pipes to be fitted and then place them on your desk. 

Be sure to check the pipes' thickness as it's one of the biggest problems with fitting.

Clean and bevel the pipes prior to cutting the ends. Start cleansing both the pipe from the inside to the outside to eliminate dirt and impurities off their surfaces. 

When you bevele, make sure that you don't exceed 1.5 millimeters of the pipe's edge and work by removing the pipe from outside. 

Then, you can proceed to cut the edges beveled for a smooth fitting.

Make use of a measuring tape to make sure the length of the pullout is precisely measured to ensure the fitting process is successful. 

The correct measurements will reduce the work to fit the pipes.

Keenly be aware of the fusion to ensure the fitting conforms to the written script. 

Before you begin fusion, make sure you've checked your parts thermodynamic properties and determine whether they're compatible. 

If you're using different pipes, you'll need to wait more time to allow the components to reach the identical temperature.

Start fitting by placing the thermoelectric element vertically on the pipes to be installed. 

While you fuse the pipes, ensure they are held in a secure position to prevent excessive rotations. Continue to hold them until the time for heating has passed.

It is possible to remove the molds when the heating time is over so that the assembly can cool. 

Be careful not to rotating the part when welding and afterwards.

Use some pressure on the cooling part of the workpiece to create a smooth weld.

Avoid Common Mistakes

From the pipes that are designed for gas and oil use to high-pressure pipes for the food and beverage industry Welders have to face various challenges when it comes to welding process.

Here are a few areas to be inspected to avoid common mistakes welding workers make:

Properly Tacking

Proper tacking is a vital step during fitting pipes. 

Cutting off the tack improves the reliability of the final weld. 

Any defect in the metal filler could affect the whole tacking process, which can help reduce the risk of this issue.

Grinding The Joint during Weld Preparation It is a typical issue among welding. 

Welders usually employ plasma or oxyfuel for preparation of the material. 

These processes produce an oxide layer over the cutting edge. 

This layer has to be removed prior to welding. Therefore, the oxides could cause porosity or other problems.

The Drive Roll The decision about the kind of drive roll you will use is dependent on the welding process. 

The type of wire you'll use will affect the best drive roll. 

In the case of use the standard V drive roll then solid wires will be the best choice. 

Copper-coated wires on the other hand, are only compatible using groove drives.

The Flow Rate of the Shielding Gas

The myth that the use of more shielding gas is the best solution to protect the workpiece has spread far and wide between welding experts. 

A high percentage of shielding gas is a waste of money and causes issues like convection effects which eventually leads to porosity. 

Utilize a flow meter regulator to control the rate of shielding gas. 

Additionally, operators and welders must adhere to the recommended flow rates.

Properly Test Your Pipe Welding

Testing is essential to determine the pipe welding's strength and weaknesses. 

Also, it is important to evaluate the quality of work that is done. 

The methods employed to test pipe welds are:

It is the Liquid Dye Penetration Test 

This test involves spraying dye on the surface of a metal and then allowing it enough time for it to penetrate. 

Once the surface has dried it will be able to see all the imperfections that were not visible are revealed.

As compared to the method of visual inspection that uses liquid dye, the test is less expensive and beneficial.

Tests using X-Rays

This technique is mostly used for tasks where the quality of welding is vital for safety reasons. 

Like the x-rays used on humans it is done by experts. 

Incredibly, it's the most reliable test welders employ to test pipe welding.

Macro Etch Testing Macro testing is the process of cutting the welded piece then polishing it and using a tiny amount acid solution. 

This allows you to test properties such as porosity inclusions, cracks and cracks' unsoundness pinholes, as well as hydrogen flake.

After weighing all the relevant elements, the last step is to install the pipe to allow welding. 

The process starts by mounting the cut-off of metal on an arm saw with a radial angle. 

The saw is adjusted or moved so that the central point of the saw is on exactly the same height as the pipe. 

The grinding process continues until the two pipe fittings are ready for welding process.


The process of welding pipes could seem complex however, with proper preparation, you will get the perfect result. 

If you practice regularly your skills will continue getting better. 

Applying these tips will guarantee your safety and success when you tackle your next project.
