Introduction When manufacturing chemical and petroleum equipment, in order to save expensive nickel, steel is often welded to nickel and alloys. The main problems of welding When welding, the main components in the weld are iron and nickel, which are capable of infinite ...Read more -
Dry information丨Copper welding technology, share it with novice welders, don’t miss it!
Copper welding The methods of welding copper (which is generally called industrial pure copper) include gas welding, manual carbon arc welding, manual arc welding and manual argon arc welding, and large structures can also be automated welding. 1.The most commonly used c...Read more -
Dry information, What factors affect welding quality?
Dry elongation Gas flow L=[(10-12)d] L/min The length of the wire protruding conductive nozzle is the dry elongation length. The general empirical formula is 10-15 times the wire diameter L = (10-15) d. When the standard is large, it is slightly larger. The specification...Read more -
13 key points to prevent welding deformation, simple and practical
Most of the occurrence of welding deformation is caused by the asymmetry of heat generated by welding and the expansion caused by different heat. Now we have sorted out several methods to prevent welding deformation as follows for reference: 1. Reduce the cross-sectional...Read more
