ND-221 TIN BRASS WELDING WIRE

COMPLY  WITH GB AWS

CU6810A --

Description:Is the content of tin and silicon special brass wires. Tin can improve the flow of wire, and silicon can effectively control the evaporation of zinc to eliminate the pores, so as to get a good weld.

Uses: suitable for brass, copper gas welding as a filler material, but also widely used in brazing steel and cast iron and inlaid carbide cutting tools. Can also be used as low pressure valve sealing surface, light load wear surface surfacing materials.

Precautions:

1. must be taken to clean the groove and wire surface before welding

2. Welding before the general preheat to the temperature of 400-500 ℃ after welding. Welding must be used in conjunction with copper gas flux or gas flux.

3. Gas welding flame should be slightly oxidized flame, the appropriate reduction in welding temperature, improve the welding speed, to minimize the pool at high temperatures to reduce the time to reduce the evaporation and oxidation of zinc
