Applıcatıons

Specifications & application fields

RW ER307 Si is used for MIG/MAG welding of dissimilar steels, low-weldability steels, armor steels, high-manganese (Mn) steel castings, rails and trusses. It is well-suited for crack-sensitive parts (e.g., crane bandages) and for stress-relieving buffer layer welds prior to hardfacing.

Dissimilar joints

Mixed steel grades

Rails & trusses

Structural repairs

Buffer layers

Before hardfacing

Weld metal performance: corrosion resistant, service temperature up to 300°C, scaling resistance up to 850°C.

Process

Production notes

Preheat & procedure

Follow WPS for preheating temperatures and pass sequence.

Control dilution

Keep dilution ratio stable on dissimilar steels and buffer layers.

Shielding gas group
