7001-1 Basic electrode for high-quality joint welds. Especially suited for root passes welding. Excellent weldability in all position except vertical-down. Smooth and slag-free welds. Crack resistant deposits of high toughness at ambient and sub zero temperatures. Very low hydrogen contents in the weld deposit.

7006 Basic coated electrode has weld metal good toughness properties & resistance to cracking. For higher weldable in all positions except wertical-down . Deposit have very low hydrogen content.

7007 Cellulosic coated electrode for the welding of pipe and pipelines in API5L X52 and X56 in all position DC only.

7008 Basic coated electrode weld metal has very low hydrogen and is extremely ductile and crack resistant. Good weldability in all positions except vertical-down. All-weld metal is 0.9 % Ni X-ray performance and usability are good.

7009 Yazd electrode 7009 basic coated can be used for welding of 0.5 % Mo steel used for high temperature and high pressure boilers chemical industries , oil refining industries and turbine casting. Other general low alloy steel and high tensile steel.

8003 Cellulosic coated electrode designed for the site welding of pipe and pipelines in API 5L X60 and X70 in all position DC only. Highly economical with vertical-down welding.

8004 Used for the welding of low alloyd and high resistant pipelines of crude oil and natural gas well as welding of pipes in larger size. Deep penetration, high mechanical properties of welding bead are the important features. Especially used in vertical down position.

8005 Basic coated electrode for the welding of low-alloy steels with impact requirements down to -60 C . The composition of the weld metal is such that good , low temperature impact properties are obtained , even welding vertically up.
