Guide to welding automotive AHSS/UHSS
This Guide provides recommendations and specifications for resistance spot, laser, and arc welding of SSAB Docol® advanced high-strength steels. For additional welding guidance. Download the full guide.
Covers best practices
The Welding Guide covers best practices for the three major welding processes used by automakers on four key SSAB Docol AHSS/UHSS steel grades:
- Micro-Alloyed (LA)
- Dual Phase (DP)
- Complex Phase (CP)
- Martensitic (M)
In many cases, welding SSAB Docol AHSS/UHSS steels is like welding mild steels — but with some important considerations, especially for ultra-high-strength steels and zinc-coated steels.
The Guide presents basic specifications and mechanical properties for LA, DP, CP, and M grades, including substrate (hot or cold rolled), applicable industry standards, available coatings, yield and tensile strengths, and elongation percentages.
