4043 aluminium alloy is a wrought aluminium alloy with good corrosion resistance typically used as filler material for welding of aluminium parts. It contains high amounts of Silicon (between 4.5 and 6.0%) and trace amounts of other metals.
ER5356 (commonly referred to as ALMg-5) is a 5% Magnesium Aluminum Alloy filler metal that is used to weld Aluminum Alloys 5050, 5052, 5083, 5356, 5454, and 5456.
ER70S-6 is a premium mild steel solid wire formulated to provide high quality welds and trouble-free performance from heavy duty, high speed, spray transfer applications all the way to light duty low speed, short arc applications. ER70S-6 is designed for use with various gas mixtures such as 100% CO2, 75/25 Ar/CO2 or 98/2 Ar /CO2. Even in the most difficult applications ER70S-6 produces a smooth stable arc with low spatter, producing a weld bead that ties in evenly with the sides and has a smooth finished appearance.
ER70S-6 is especially suited for sheet metal applications, where smooth weld beads are desired, and structural and plate steels that have moderate amounts of rust or mill scale.
ER308L is designed for welding austenitic stainless steel type 19 Cr 10 Ni or similar. The filler metal is also suitable for welding titanium and niobium stabilised steels.ER308LSi has enhanced silicon contant(0.85%) which improves the fluidity of the melt pool with a minimum of spatter and porosity.
Welding is performed using direct current negative polarity (DC-). Welding can also be performed using pulsed current, which can be advantageous when welding in positions and for the welding of thin gauges. Shielding gas recommendations: the most frequently used shielding gas is pure argon (Ar) with a gas flow of 6-8 l/min. Addition of about 30% helium (He) or 1-5% hydrogen (H2) will increase the energy of the arc. This will give a wider weld and a better fluidity of the melt pool.
ER309L is a high alloy 23Cr 13Ni wire primarilay intended for surfacing low-alloy steels and for dissimilar welding between mild steels and stainless steels, offering a ductile and crack resistant weldment.
Stainless steel 316L is still the most commonly used SS material in the jewellery and watch industry; this is austenitic Stainless Steel.The letter itself stands for Low (meaning Low carbon) L grades have 0.03% carbon maximum.
904L is intended for welding 904L and similar grades. 904L is very well suited for use in constructions of the ASTM 316 type, where a ferrite-free weld metal is required, e.g. in cryogenic or non magnetic applications. The impact strength at low temperatures is excellent.
904L has a relatively good resistance, provided that the welding has been carried out carefully i.e. by minimizing the dilution and by keeping the heat input at max 1.5 kj/mm. The material should also be allowed to cool down to 100ºC before the next run is welded.
