Free sample Pure copper welding wire aws a5.8 ercu 2.4mm 1.2mm for copper sculpture

Description:

S201 is a deoxidized copper wire containing silicon, manganese, manganese and phosphorus and other trace elements. Silicon, manganese and phosphorus are mainly added as deoxidizer, and tin addition improves the mobility of molten copper.
Advantages: welding copper with excellent welding performance, good weld forming, high mechanical properties
Use; for copper argon arc welding, gas welding, and plasma arc welding. Such as billet and other continuous casting mold, steel mill fixture, conductive roller, conductive plate, heating the original, copper and copper sculpture, etc.

Precautions:

1. For TIG welding (tig welding), must be preheated before welding, the thickness of less than 3mm, the preheating temperature of 150-300 ℃, plate thickness greater than 3mm, preheating temperature of 300-550 ℃
2. For the base metal welding, should give priority to the melting of welding (welding welding). When the thickness is less than 6mm, it is usually not necessary to preheat, the plate thickness is greater than 6mm, the preheating temperature is 200-500 ℃
