Welding wire

Effect of silicon content when MIG welding
Avesta MIG/TIG wires are available with a low or a high silicon content. High silicon content gives better arc stability and better fluidity when MIG welding. This also gives a more attractive weld surface and reduces the porosity as well as the spatter. These advantages are particularly pronounced when short-arc welding. In AvestaPolarit Welding´s range of welding wire, the high-silicon type is only available for welding materials where unaffected resistance to hot cracking has been demonstrated in connection with welding.
The submerged-arc wire is made only with low silicon content, since most granular fluxes give rise to silicon alloying, and high silicon level can cause hot cracking.
