Procedures and parameters for gta welding of stainless steel in thick nesses from 1 16 inch to 1 2 inch 1 6 to 12 7 mm are given in figure 18.
Stainless steel welding electrodes specification.
For stainless steel stainless steel electrodes are designated in a slight different way.
An e308h electrode however must have at least 0 04 c up to a maximum of 0 08 c.
This can be difficult to control.
Carbon content in the range of 0 04 0 08 provides higher tensile and creep strengths at elevated temperatures.
Specification for stainless steel electrodes for shielded metal arc welding 1.
Suitable for welding ferritic stainless steel of aisi 430 422 446 grades chromium castings burner parts equipments of chemical textile and food industries hardness of weld is around 250 280 vpn.
1 2 1 4 3 8 5 16 50 piece pack.
Coatings with high iron oxide content produce a weld deposit with a large amount of slag.
Valves and valves parts and turbine components hardness of weld is around 375 400 vpn.
Welding of clad plate is a specialized area of dissimilar metal welding and beyond the scope of this course.
These electrodes are good arc gouging electrodes and great for cutting steel high temperature alloys aluminum copper and stainless steel.
1 8 3 16 5 32 100 piece pack.
Some of the commonly used stainless steel electrodes are er308l and er309l etc.
Meaning of these symbols is explained below.
An e308 type stainless steel electrode must have a maximum of 0 08 by weight of carbon c.
5 12 stainless steel electrodes and filler metals there are several different forms of stainless steel electrodes.
1 covered stainless electrodes arcaloy covered stainless steel electrodes are classified according to the american welding society filler metal specification a 5 4 92.
This coating type produces high speed deposition and provides medium penetration with low spatter level.
Scope this specification prescribes requirements for the classification of covered stainless steel electrodes for shielded metal arc welding 1 chromium content of weld metal deposited by these electrodes is not less than 10 5 percent and the iron.
These include butt corner tee and lap type joints.
Covered continuous solid bare continuous flux cored and cut length bare welding rods.
