Why am I getting holes in my TIG welds?

Why am I getting holes in my TIG welds?

Paint, oil, grease, and rust can all cause pinholes to form in the weld bead. This is particularly important in TIG welding. The electrode and rods used for TIG welding don’t have any flux to clean a weld or handle impurities. You must get everything clean before you crack an arc.

What is the best filler rod for TIG welding?

Aluminum. ER4043: is a good general filler material for most aluminum applications. However, welding of 2xxx and 7xxx series aluminum is generally not recommended. ER5356: is used for 5xxx series aluminum and is generally preferred if the finished piece will be anodized.

What causes pits in welds?

Pits. Pits (open defects) are surface defects produced when gas cavities formed inside the weld metal solidify after the gas escapes from the bead surface. Gas cavities remaining inside the bead are an internal defect known as blow holes.

What size TIG filler rod should I use?

Generally speaking, use 1/16″ diameter filler rod for applications where the material is 1/8″ or less, and use 3/32″ diameter filler rod for applications where the material is 1/8″ and thicker.

How do you prevent holes when welding?

Burn through happens when your welder is set to a higher amperage which makes a hotter weld while at the same time welding a thin piece of metal causing it to blow through the metal creating a hole. To prevent this you need to turn down your amperage and make smaller welds to keep the base metal from getting too hot.
