Plasma-Transferred Arc (PTA) welding is the most advanced welding process available for situations involving extreme abrasion. The robotically applied process uses ionised gas to create a very controlled heat-input. The low heat results in minimum distortion and dilution, which enables maximum hardness in a single layer. Avweld, with over 30 years of material engineering experience, have created several alloys for specific applications, which provide the ultimate level of resistance for combinations of wear factors such as abrasion/impact. PTA welding provides the highest quality wear-resistant solutions for a wide variety of situations.
PTA provides similar material properties to laser welding or cladding.
