LY-ER49-1

符合

GB/T ER49-1 (H08Mn2SiA) EQUIVALENT NORM:AWS ER70S-7 DIN S G3

Description:

LY-ER49-1 is a carbon steel and low alloy steel gas-shield welding wire. It is able to prevent gas porosity and slag inclusion producing due to the de-oxidization depending on Mn and Si in the wire jointly.The crack resistance of weld metal can be developed and satisfactory mechanical properties can be obtained .Molten steel flows smoothly and weld seam has a high crack resistance as well.

用途:

Suitable for single-pass and multi-pass welding for structures fabricated by carbon steel and 490MPa grade low alloy steel,such as vehicles,bridges, construction and mechanical structures etc.

INSTRUCTIONS:
a.Suitable for using shielding gas at the speed of 20-25 liters per minute.
b.Windshield must be set up in the welding zone,due to gas porosity may be caused by strong wind.
c.Wire extention should be 10-20mm if the current range is under 300A and if above 300A,20-25mm.
