Fit-up in welding is defined as the degree of contact between connecting parts. Part fit-up is amongst the standard procedures in pipe welding. By rushing this process there is a chance of misalignment welding defects that causes the joint to be asymmetrical and structurally weaker.

The best fit-up tools can ensure that the pipe gets up in a level and ergonomic work height, then the pipe clamps and fit-up tools properly align the pipes in preparation for welding ensuring no defects in the end product.

Welding by itself is a process that joins materials by melting them together and then allowing them to cool causing fusion. Joining two pipes together is called pipe welding or pipe fabrication. There are multiple methods to achieve this process like Arc Welding, MIG Welding, TIG welding and several other techniques.

Let’s take a look at some best practices for pipe welding:

Proper Preparation

Preparation of the pipes begins with ensuring that the edges of the two pipes to be joined are smooth and uniform. A surface grinding procedure is used to get the edges right when relevant. Then the pipes are cleaned to remove any form of lubricants or oils from the surface.

Avoid Misalignment

There is a limit to what can be achieved by the filler material in adjusting to resolve the misalignment between two pipes. A standard feature in pipe welding is part fit-up. Use welding fit-up tools to ensure proper welding.

Follow The WPS (Welding Procedure Specification)

This document contains information for welders, assisting them in making welds that are in line with the code requirements. For example, weld types, welding positions, filler classifications, temperatures, weld treatment and more. It’s a very good idea to refer to this document before starting the welding process.

Follow The Correct Weld Procedure

Process for welding changes according to the type of welding used. What is relevant for one type of welding will not be relevant for another type. Following the correct weld procedure will make sure you do not end up with defects.

Correct Amount Of Shielding Gas

Shielding gas is used to prevent the weld from interacting with atmospheric gases like Hydrogen and Nitrogen. Using a flow regulator is recommended to ensure the weld receives the correct amount of shielding gas.

Negate Porosity

Factors like using the wrong gas, changing the wire spool or not prepping the workpieces can cause porosity in the welds.

Anyone can make a mistake while welding, following the pointers above will ensure a successful welding job.
