Lightweight structural transition joints are widely used in the fields of shipbuilding, rail transit, and mechanical manufacturing due to their excellent welding, corrosion resistance and durability. Phohom's clad bi-metal weld transition joints are trusted by our customer.
Structural transition joint between steel and aluminium are increasingly made with transition plates, it can eliminate the risk of corrosion and provide better welding intensity and service life while achieving lightweight design and increase speed.
Aluminum-steel welded transition joint is generally cut from the flat plate. Normal shipbuilding aluminium alloys can be welded to the alminium side and steels to the steel side
