Can you weld 7guage material with a 120volt mig welder?
yes
What is remedy to prevent slag inclusions?
Remedies to prevent slag inclusions - Avoid atmospheric contamination using proper welding procedure e.g. adequate Shielding Gas Proper removal of slag from weld bead surface using wire brush Redesigning the weld joint to permit sufficient space for manipulation of the puddle of molten weld material
Butt-weld and grrove weld?
First, Butt-weld is short for a butt groove. Welding in a butt-groove starts at the throat of the butt-groove. The first weld point could be a tack-weld: holding the two materials to be welded together. The throat is measured and filler metal and electrode are determined to create the root pass.
What is peening in welding?
It is one way to "Stress Relieve" the weld joint. As the weld metal metal cools it contracts and hammering on the weld expands it. On thick sections it is done after every layer of weld. Often used when welding cast iron or other metals with a low COE (Coefficient of Expansion).
Is there required size for a seal weld per AISC?
The required size for a seal weld per AISC is eighteen foot length. AISC also specifies minimum weld size based on the thicknesses of the members joined.
Sae 4130 weld with st52 material which filler rod use?
Use Hastaloy X
What is the effect on the weld if the electrode is held too close to the material being weld?
the rod will simply stick to the material being welded!
What does it mean by the crown of the weld?
The crown of the weld is the material of the filler metal that projects above the surface of the parts being joined by the weld.
What filler metal is used to weld 308 stainless steel to 316 stainless steel material?
You can use the 308 or 316.
Can you weld 7guage material with a 120volt mig welder?
yes
Why it is eassy to weld hard material than ductile?
it is not easy to weld hard materials....it always difficult to hard materials.....
How to polish weld when completed?
A weld is covered with slag - the material used to protect the arc - after welding is completed. It can be chipped off with a sharp tool or brushed off. A weld is usually rippled on the surface and is not usually smooth. The best way to polish it is to use a soft brush of some type.
How do you calculate weld deposit metal weight?
At first, the area of cross section of the weld, length of the weld, volume of the weld in cubic inches, weight of weld in cubic inches. To express in formula: Weight of Weld Metal = _ Êx ÊBase Êx ÊHeight Êx ÊLength Êx ÊWeight of Material.
What is the material used for tac welding?
Tac welding is not a specific material. Tac welding is a form of welding, that welder's use in order to hold two pieces' of metal together to get a proper fit. The tac weld can be easily broken if the two pieces' of metal aren't in the right place. So if you tac weld anything, the filler is going to be whatever material you are welding.
How do you measure filet weld?
In a fillet weld, the leg and size are the same for the convex weld.
What is a fusion weld?
A fusion weld has no filler material. The pieces to be joined are touching and heat is applied at the joint. The edges melt and "fuse/weld" together. TIG or Oxy-fuel Welding is used. This type of welding is considered to be pure as nothing is added to the weld.
What is the effect on the weld is the electrode held closely to the material being welded?
the rod will simply stick to the material being welded!
