ER4043
Category:
Product Introduction
Application: Used for the welding of relevant aluminium alloys e.g.ships,locomotives, chemical engineering,food,sport appliances,moldings,furniture,vessels,containers, automotive industry and structural components e.g.6xxx series aluminium alloys etc.
Characteristics: YH4043 is one kind of aluminium-silicon alloy welding wire with silicon content is 5%.It has good welding properties with beautiful formation of weld,stable electric arc and less splash.It has a lower melting point and better fluidity compared with 5xxx series aluminium alloy with a lower hot cracking susceptibility.

Note On Usage:
1.It is required to remove the oxidation film and oil contaminant from the welding edge workpiece and surface of welding wire.
2.Itis able to support the molten metal with a plate during weldng to ensure the formation of weld.
Used for high eficiency welding in all positions with excellent welding performance such as warming electric arc,little spatters,beautiful seam forming and easily moved slag.Suitable for welding of 590 MPA high strength steel,steel structure,bridge,steel pipes,railway vehicle,and construction equipment etc.
