GL52 - AWS E7016/ JIS D5016

Product Description

For welding class high tensile steels

• 1. Characterics on Usage:
• GL**2 is a low hydrogen type covered electrode with excellent usability in all position welding.
• GL**2 is suitable for medium tensile strength carbon and alloyed steel in ships, bridges, building, and pressure vessels.
• It's easy-slag-removable, few blowhole, smoke and spatter. Its weld bead is smooth, shinny; the arc is soft, the re-striking is good and the penetration is shallow...especially having perfect result with AC current.

• 2. Typical chemical composition of (deposited) all-weld-metal (%):

   

  C	Mn	Si	P	S
  0.*0 max	1.0 ~ 1.*0	0.*0 ~ 0.*0	0.**5 max	0.**5 max

   

  4. Typical mechanical properties of all-weld-metal:

  Tensile Strength  (MPa)	Yield Strength  (MPa)	Elongation  (%)	Impact Value  0oC ( J )
  **0min	**0min	*2min	*0min

  5. Size available, recommended currents (AC&DC):

  Size ( mm )		Ø3.2	Ø4.0	Ø5.0
  Length    ( mm )		**0	**0	**0
  Welding Current Range (Ampe)	F	**0 – **0	**0 –**0	**0 – **0
  	V & HO	*0 – **0	**0 – **0	**0 –**0

  6. Usage introduction: 

• Dry the electrodes at ******0^oC for ****0 minutes before use.
• Adopt the backstep method or strike the arc on a small steel plate prepared for this particular purpose to prevent blowhole at the arc starting. 
• Keep the arc as short as possible
