At ARCOR, our engineers are experts in choosing the right materials for weldability. Here are some guidelines that may help you pursue your next project. If you have questions, please contact us! We regularly consult with clients in the R&D stages of their product design process.
Materials with good weld properties
- Stainless steels (303 SS not recommended for welding)
- Low-carbon steels
- Nickel-based alloys
- Aluminum alloys
- Refractory alloys: zirconium, titanium, tantalum, niobium
Materials with difficult weld properties
- Medium to high carbon steels
- Cobalt alloys
- Copper and copper alloys
- Tungsten, cast iron and certain tool steels are difficult (but can be welded with proper preparation and techniques.)
Materials that are not suitable for Laser Welding Process
- Materials with low vapor and heat characteristics
A special note: Materials containing sulfur, phosphorus, or selenium usually containing higher than .03% and materials that have oxygen content are to be used with precaution and not recommended. Please note that these are generalities and certain alloys or alloy combinations are more difficult to weld and may need special care or techniques. Please call to discuss weldability prior to your final material selection. For more information, please contact us.
