Its principal target is to prevent cracks. To avoidthem, preheat and keep the area to be weld,between 140-180ºC. We recommend to use agas torch, and control temperature withtemperstilks or contact or radiationpyrometers.
Maximum Temperature and ﬁnal check
During the welding process, do not go over250ºC, except the direct aﬀected parts. Thebest method to keep the temperature withinthese limits, is to space each run. Whenﬁnishing the welding, it is essential to check thequality of the surface of the ﬁller material andthe absence of defects. The surface of beadsmust be as ﬂat and regular as possible. Grindthe irregularities, avoiding parallel grindinglines to the beads.
GMAW procedure (Gas Metal Arc Welding)
When it is done with gaseous protection, formoderate thickness and requirement welding,we recommend to use welding wire with solidthread. For high thickness and highrequirement welding, use welding wire oftubular thread (Flux-core)
