GB/T 25776-2010Qualification methods of welding procedure for welding consumables (English PDF)

2.1 AC arc stability

When AC welding power welding arc to maintain the stability of combustion.

2.2 De slag detachability

Ease of slag from the weld surface of the shell off.

2.3 Then arc performance reignitioncapability

Stop some time after the welding arc, the ability to re-ignite the arc.

2.4 Spatter

The amount of spatter loss and melting wire (or rod) percentage amount.

2.5 Melting coefficient

Welding process, the current units, per unit time, the core wire (or wire) of the melting capacity [g/(A · h)].

2.6 Deposition efficiency

The amount of deposited metal with the molten filler metal (core wire or wire) the amount of percentage.

2.7 Welding dust generation totalamountofweldfumes

When soldering, welding fume per unit mass of material (rod or wire) produced [g/kg].

3.1 General principles

In the absence of special assessment requirements, the use of welding current 90% recommended by the manufacturer of the maximum current, AC and DC welding material mining

AC welding, welding voltage and drying specification uses recommended by the manufacturer specifications. In addition to nickel, copper, aluminum with the corresponding test panels, the other welding materials

Material to use its considerable chemical composition of deposited metal test plate or a carbon content of no more than 0.2% carbon manganese steel plate welded structure surface of the test shall be subject to

Grinding or machining to remove the oil, scale and the like.
