Q. What tools do I need to gas weld aluminium?

• Stainless steel or brass brush to clean the work 

• Contaminates.- (do not use this brush for any other work).

• A gas torch eg. Propane, LPG, oxy-acetylene, MAPP.

 
Q. Is aluminum gas welding dangerous?

• Wear safety glasses and protective clothing

• Ensure good ventilation.

Q. What is the cost of gas weld aluminium welding rods?

• Please click the "How to order" link for current prices.

Q. What is most important when gas welding aluminium?

• Ensure all oxide and contaminates are removed with a stainless brush.

• Warm the target to a sufficient temperature that willmelt the rod and move the melting rod over the join.

Q. Is gas welding aluminium easy to do?

• Like all procedures it takes a little time to becomefamiliar with the process -View the video link for more

       information.

Q. Is an aluminium gas weld strong?

• The rods create a strong durable bond.

• The weld is stronger than the aluminium

 

Q. Do I need to use flux with aluminium gas welding?

•  These rods require no flux.

Q. How thin can aluminium sheet be for a successful gas weld?

• Use the rod as a thermometer or heat gauge.

• The only variation is the amount of heat put into the base metal.  The thickness of the base metal is irrelevant.          

• See video for welding thin aluminium cans .

 
Q. Can I gas weld at home?

• Yes

Q. How to prepare aluminium for gas welding?

• Remove any paint, oil, grease or dirt impregnated in the metal, eg a sump. Vinegar or muratic acid may work.

• Remove any seals. You may angle grind or file.

• Final cleaning is done with a dedicated stainless steel or brass brush. The metal should be shiny.

 
Q. What makes a successful aluminium gas weld.

• Success is achieved when the clean base metal is hot enough to melt the rod (380C)

• For cracks or broken pieces, tin both sides of the crack with the rod, then puddle in.

• For holes, tin around the hole then puddle in.

• See video for details.

 

 Q Can die cast be welded?

• Yes. Die cast comes is a variety of qualities from bellhousings to car door handles.

• See brochure under Die Cast for details.

 

Q Can copper be repaired

• Yes. Use the same technique as aluminium. Longer heating of the copper may be required.

• Not suitable for plumbing.

 

Q Can brass be welded?

• Yes. Use the same technique as aluminium. Longer heating may be required.

 

Q Can bronze be welded?

• Yes. Use the same technique as aluminium. Longer heating may be required.

 

Q What metals will the rod not weld?

• The rod will fuse with non-ferrous metals includingaluminium, die cast, copper, brass and bronze.

       It will not fuse to any ferrous metal. This includes iron, cast iron or steel. If a magnet will stick to it, the rod will not.

 

Q Can galvanised steel be welded?

• Yes. The coating, mainly zinc, will be fused. Not the steel.

 

Q Can zincalum be welded ?

• Yes. The coating ,zinc and aluminium, will be fused. Not the steel.

 

Q Can models be welded?

• Yes. Alloy in models is usually light guage.

        Because the rod melts at such a low temperature, 380C, the metal will not be adversely affected.
