Based on our experience we recommend electric welding process for connecting valves or strainers with tubes or with each other Lime based electrodes with an appropriate composite material should be used as filler material for welding.

Gas welding should be avoided.

Due to the different material composition and material thickness of valves and tubes, gas welding is more susceptible to produce faults than electric welding (hardness cracks, coarse-grained structure).
