First ,we must confirm the welding way. There exist electrical welding, submerged arc welding,tungsten argon arc welding,gas shielded welding,etc. The welding engineer shall make the WPS and PQR for the workingpiece in advance. Then welders can follow the WPS & PQR to act correctly.
Such as hand arc welding, submerged arc welding, tungsten argon arc welding, gas metal arc welding, etc., there are many types of welding methods, and can only be selected according to specific conditions. Only the welding method be confirmed can we start to make the welding process parameters .The types of welding process parameters are different. For example, hand arc welding mainly includes: welding rod type (or brand), diameter, current, voltage, welding power source type, welding Number of layers, number of tracks, inspection methods, etc.
As for a good conveyor’s factory ,there must be with a good welding engineers.Wuxi Changrong has an experienced welding engineer and a team of excellent welders to work together. Therefore,all conveyors are exported to abroad and are very popular in over sea’s market.
