The basic method of fusion welding that uses the squeeze and heat process is?
thermal
What is post weld heat treatment?
post weld heat treatment is done on the weld areas after welding, to remove the residual stress present in the welded part formed during the welding process, it prevents to cause brittle fracture in a metal
What are the effects of heat input and the effects of the rate of cooling and heat distribution during welding on the grain structure of two given welded joints?
If you have no idea - don't write anything..
What is Cold rolled ganvanized steel?
Steel which has been rolled out at temperatures below red heat, and then coated with zinc.
Which steels are used in heat treatment and its components?
stainless steel
Is it required to do pickling and passivation on Tube to tube sheet welding on Stainless Steel Heat exchangers?
yes

Why is acid used in pickling foods?
After welding for instance stainless steel tubing the welds are pickled in order to remove the discoloration of the heat.
What would be a good sentence for specific heat?
To be effective, this welding rod must be brought to a specific heat.
In ultrasonic welding what creates the heat required for welding?
What creates the heat is the flame inside the torch
What is the difference between arc welding and resistance welding?
in arc welding only heat is used to weld metal. but in resistance welding pressure will also be used along with heat.
What is the welding procedure for welding P22 pipe to 304 stainless pipe?
I have not welded P22, but from what I read it is a low allow stainless that tends to get brittle. The welding techniques specified include a pre and post heat treat and on thicker materials a buffer layer of 316L with the final joint of 309 not sure what p22 pipe is but if it is carbon you should use a 308L filler with 100% argon purge 308L is a filler for fusing carbon steel and non carbon stainless. If it were 316 stainless you would want to use a 319 filler P22 is a steel alloy containing 2 1/4% chromium. It is weldable with most carbon steel alloy fillers such as E-70s2, ER-7018, etc. However, to weld it to a low grade stainless steel alloy such as 304, you would need to use a bi-metal welding alloy such as E-309, or ER-309. The above answer is incorrect regarding 308L being a filler for carbon steel to stainless steel. It is in fact 309 which is used for dissimilar metal welding when one component is stainless steel. I have also had good success welding two dissimilar metals together using inconel alloy welding electrodes such as INCO-182.
What causes metal to creak?
I am a welding student so I do indeed know alot about steel's/welding metals. In steel there is a cell like bond. Such as in anything else. Once heat or strees is applied you force the steel to change cell shape causeing the creak you hear, its mostly stress of the steel. This can be prevented by following pre-heating guidelines or limiting the stress on the steel. And do remember everything has a limit...so dont push to much! hope i helped
Laser welding machine welding stainless steel?
Laser Welding of Stainless Steels Stainless steel materials are used in a wide variety of applications because of their enhanced corrosion resistance, high temperature oxidation resistance, or strength. Stainless steel’s unique properties are derived by adding alloying elements, principally chromium and nickel, to steel. Typically, more than 10% chromium is required to produce stainless steel. There are four general grades of stainless steel, which are typically classified according to their material properties. Listed below are laser welding considerations and requirements for each grade. Austenitic stainless steels The 300 series of stainless steel is generally austenitic stainless steels. These stainless steels are used in applications requiring corrosion resistance and toughness. The 300 series stainless steels can be found in a wide range of applications in petroleum, transportation, chemical, and power generation industries. These stainless steels are particularly useful in high temperature environments. This series of stainless steel is suitable for both pulsed and continuous wave (CW) laser welding. Laser welding stainless steel provides slightly better weld penetration depths and increased weld speeds when compared to low carbon steels due to the lower thermal conductivity of most austenitic stainless steels. The higher speeds from laser welding are also advantageous in reducing the susceptibility to corrosion caused by the precipitation of chromium carbides at the grain boundaries. Chromium carbides precipitation can occur when the heat input is too high during the welding processes. The well-controlled and repeatable heat input from the laser welding process reduces the width of the heat-affected zone, thus reducing the region that may be susceptible to pitting and corrosion in the future. An additional benefit from laser welding these grades of stainless steel is reduced thermal distortion and residual stresses when compared to conventional welding techniques. This is especially important for stainless steels that have a 50% greater thermal expansion than plain carbon steels.
What is the term tw refers to in welding?
TW = thermite welding, a welding process that requires no external source of heat or current.
What is used in welding?
A device that can generate heat. Melted material and the welding operation is performed.
