ARC (Stick) Welding, also known as Shielded/Manual metal arc welding allows weld repairs to be carried out in most weather conditions and on most types of steels including badly corroded steel.
MIG Welding
Also called Gas metal arc welding, this type of welding allows for strong, reliable welds to be carried out quickly and cleanly. It is particularly useful for heavy aluminium repairs.
Flux Core Welding
This is similar to MIG welding but can produce even stronger welds for heavy repairs.
