flash·back (flshbk)n.1.a. A literary or cinematic device in which an earlier event is inserted into the normal chronological order of a narrative.
b. The episode or scene depicted by means of this device.
2. An unexpected recurrence of the effects of a hallucinogenic drug long after its original use.
3. Psychology A recurring, intensely vivid mental image of a past traumatic experience: "Another study shows that women who served in Vietnam still struggle with depression, anxiety, and painful flashbacks from the war" (New York Times).
backfire
- A torch malfunction in which the flame moves up into the tip of the torch. Backfire is fairly common and is not a major safety concern.
- Learn more about backfire in the class "Oxyfuel Welding Safety 105" below.

In welding, backfire occurs when the flame temporarily travels back into the torch due to a momentary interruption in the gas flow, often resulting in a loud popping noise. Flashback is when the flame travels back into the torch along with the mixed gases, causing a sustained burning within the torch. Both backfire and flashback can be dangerous and should be addressed immediately to prevent equipment damage or injury.

What is different between fusion and non fusion welding?
Fusion welding joins materials by melting them together, while non-fusion welding joins materials without melting them. Fusion welding includes processes like MIG, TIG, and arc welding, where a filler material may be added. Non-fusion welding methods, such as friction welding or ultrasonic welding, rely on pressure or friction to create the bond between materials.
Definition of argon welding?
Argon welding, also known as gas tungsten arc welding (GTAW), is a welding process that uses a non-consumable tungsten electrode to create a welding arc. Argon gas is typically used as the shielding gas to protect the weld pool from atmospheric contamination. This process is commonly used for welding non-ferrous metals, stainless steel, and thin materials.
How is the welding operation stopped when the arc welding is stopped?
The welding operation is stopped by moving the welding torch away from the workpiece to break the electrical circuit and extinguish the welding arc. Additionally, turning off the welding power source or releasing the welding trigger can also stop the welding operation.
What are welding sparks called?
The sparks generated during welding are called welding sparks. They are tiny fragments of molten metal that separate from the welding material or workpiece due to the intense heat generated during the welding process.
What is Limitation of gas welding?
One limitation of gas welding is the limited range of materials for which it is suitable, as it may not work well with certain metals or thicknesses. Additionally, gas welding can result in slower welding speeds compared to other methods like arc welding. Maintaining the proper gas pressure and flow during gas welding can also be challenging.
what- flashback definition?

What is the definition for CSWIP?
Certification Scheme for Welding and Inspection Personnel
What is the definition skilled trades?
Skilled trades are jobs that are done with the hands such as construction, plumbing, and welding.
a summary of backfire?
Like if you and your girlfriend or boyfriend break up then they going to try to find somebody like your friend and try to backfire you and say now look who I got she's prettier he handsome than you and then that's not going to be right cuz it's going to be really rude and stuff so that's a definition of backfire.

What is the definition of heat fusion?
heat fusion is to join things together by heat. ie plastic welding.
