Pressure Vessel WPS Welding Materials – Welding Material Consumption Quotas
Thread Content
Gentlemen: How is the consumption quota for welding materials in the WPS of pressure vessels calculated?
For ordinary containers, an estimate of around 3% is used for the weight proportion of welding electrodes.
Hello, teacher. I just want to know the exact amount of welding material used for a single weld
That involves performing specific calculations: based on the type of weld and the shape of the weld groove, the amount of weld metal that needs to be filled is determined, taking into account factors such as root cleaning and excess weld material. For submerged arc welding wires, a coefficient of 1.05 is applied; for electrodes, approximately 48% of the weight of the deposited metal is considered.
Just calculate the volume of the weld, and that way you’ll have the weight Just multiply by another coefficient
