Q235 plate thickness 4mm-5mm what is the diameter of the wire to be selected by submerged arc welding what is the flux?
With two oxygen bars? 4-5mm steel plate is too thin, it is not suitable to bury the arc current
In fact, 4-5MM has a special submerged arc welding 1.6 wire, that is automatic two welding machine, remove gas and welding flux. Or use 2.5 of the wire,
It's a bit thin. If we want to use submerged arc welding, we can add padding on the back, welding on one side and forming on both sides. The gap is 2mm.The welding wire is 4.0mm H08MnA and the flux is HJ431.Let me give you an arc welding current empirical formula: I= (100~200) x wire diameterEmpirical formula for estimating penetration depth: I weld penetration - 1mm/100A
