Characteristics and Application
AWS A5.4 E308H-16 Welding rods, welding electrode is a titania type electrode. The weld metal is austenite limited + ö -ferrite structure The product features excellent performances in slag release, weld bead appearance, weldability, corrosion resistibility at high temperature. It is suitable for the welding of AISI-304 steel, AISI-301 steel and AISI-302 steel in all positions. Proper base metals are including stainless steel plate, steel tube, steel strip, seamless pipe, heat transfer tube, pressure vessel and steel bar.

Notes on usage:
1 . Clean up the contaminations on the base metal, groove and pass to pass with stainless steel brush.
2. Maintaining short arc length as possible is highly recommended. While welding with weave method, moving range should be controlled within 2.5 times of the wire's dia.
3. Dry the electrodes at 250—300℃ for 60 minutes before uses Take out consumables for half day consumption and keep in the environment at 100-150℃ during welding process.
4. Use lower current to prevent from crack and minimize base metal dilution.
