Latest development for automotive applications!
With the electrode bercoweld S2, welding and brazing processes of automotive engineering can be significantly improved. This new copper electrode for welding and brazing provides optimized flowing properties, better ability to bridge root openings and higher processing speed.
bercoweld S2 (354KB)
This welding filler metal is particularly recommended for the use of coated sheets for the car industry. Good flowing properties of weld pool, no tendency to porosity and spatter. Suitable for welding of Cu and Cu-alloys as well as low and unalloyed steels and cast iron.
MIG – pulsed-arc welding is recommended.
WIG – for sheets thicker than 3,00 mm preheating to apprx. 250-300 °C is recommended.
