ERW tubes are welded to give them their shape. One of the most important processes in welding is preheating. People use this to guarantee weld quality. Moreover, it lowers the chances of cracking and other complications that arise. These can be expensive to fix. Welding preheat tends to be utilised prior to welding steel, or its alloys, that are an inch thick or bigger. It is a process that is typically a necessity in field and shop welding for gas and oil products. Other applications include heavy equipment, mining, and structural construction.

The procedure

ERW steel tube supplier West MidlandsThe preheating procedure consists of you heating the area surrounding the weld joint or the whole part. You do this to a set temperature prior to welding. This minimises the weld’s cooling rate. Furthermore, it drives moisture out. What this does is assist you in stopping hydrogen from accumulating. The potential for cracking is greatly diminished too.

You can use a number of approaches for welding preheat. The list includes convection ovens, resistance heating, open flame, and induction. Each one has its pros and cons depending on what application it is you are working on. The most ideal technique for a certain application depends on a number of factors. These can include expertise, weldment size, available personnel, budget, and project timeline.

Do I need to preheat?

Figuring out whether your welding application demands preheat depends on multiple details. This includes the thickness and type of base material. It is normally dictated by the welding code you are using.

To meet the welding code’s requirements, the job’s welding procedure specification is going to define the maximum and minimum preheat temperatures. It will do the same for the duration of preheating. In many cases, you have to hold a part within a certain temperature range for a specific period of time. This is before you can start the welding. For example, it could be between 250ºF and 400ºF for half an hour.
