What are the welding parameters that must be consider to produce quality weld?
Wiki User
∙ 9y ago
the metals to be welded should be placed correctly, the dust on the metals should be removed, the distance between the metals and electrode should be maintained, proper current must be produced on the basis of metal thickness.

How can someone make a Welding Procedure Specification?
A Welding Procedure Specification (WPS) is a document that provides variables and conditions of a welding procedure that is produced for a very specific application. To write one properly, experimentation and calculations must be done to find the correct parameters for the procedure. To generalize, a WPS must include all known parameters of the process; including process type, current, current type, voltage, shielding gas type, shielding gas flow rate, base metal, electrode type and size, filler metal type and size, joint design, and travel speed. There may be more variables than listed, depending on the application. One must also remember that on a WPS, ranges for variables are used that are adjustable by the welder or welding operator. Ex. Current (Amperage) 150-170 A instead of just saying 155 A. To find these ranges is where calculations are necessary.
What is laser beam welding used for?
Laser beam welding is generally used for joining together components that require thin seams and minimal distortion. The process is finely directed and offers an excellent quality finish and this is why it is a popular method for making jewellery, cars and computer components.
What is the significance of the arc welding process?
The significance of the arc welding process are:-1. Flux Shielded Manual Metal Arc Welding is the simplest of all the arc welding processes.2. The equipment can be portable and the cost is fairly low.3. This process finds innumerable applications, because of the availability of a wide variety of electrodes.4. A big range of metals and their alloys can be welded.5. Welding can be carried out in any position with highest weld quality.6. The process can be very well employed for hard facing and metal deposition to reclaim parts or to develop other characteristics like wear resistance etc.ARSHAD H BHUTTOSALES ENGINEER-LINCOLN ELECTRIC WELDING PRODUCTS
What does a welding engineer do?
A welding engineer is a person with the demonstrated education, experience, and knowledge in specialized fields of welding, brazing, cutting and materials joining. Welding engineering is a broad field that covers fields from automotive and shipbuilding to nuclear power, areospace and mining. If there is joining of metals involved then there is probably a welding engineer involved the in the process. A welding engineer is capable of directing those operations associated with weldments and other types of joints that are completed in accordance with the appropriate contract documents, codes, and other standards to produce a satisfactory product. The welding engineer's activities begins before production or construction welding and continues through the production process then ending when the production process is complete. This may include NDE, materials science, filler metal control, corrosion control and repair welding. Most Welding Engineering curriculum's are built on a solid general engineering, calculus-based, foundation that includes course work in mathematics, physical metallurgy, physics, chemistry, engineering mechanics, thermodynamics, fluids and other core engineering requirements. See Ohio State University for information on 4 year ABET accredited welding engineering degrees.
What are applications of explosion welding over conventional welding?
The biggest application of explosion welding is the cladding of flat plate.
Why is dc welding develop?
we will have straight polarity and reverse polarity,we can produce the weld with good quality
What welding parameters to consider to produce quality weld?
There are 4 basics to producing a good weld bead. Correct #1 Amperage #2 Electrode Angle #3 Arc Length #4 Travel Speed Factor in electrode manipulation in some cases.
What type of welding is used in welding LPG gas cylinders?
What type of welding can we use LPG ?
How does a welding transformer work?
A welding transformer uses the alternating current supplied to the welding shop at a high voltage to produce the low voltage welding power
What are the variable parameters for TIG welding?
The variable parameters for gas tungsten arc welding (GTAW) include; current, arc length, electrode type, electrode size, electrode grind angle, shielding gas type, shielding gas flow rate, and travel speed.
How is oxygen used used in welding?
Oxygen is used to produce hot flame which is used in welding purpose
Does stainless steel welding require gass?
Most welding processes produce a gas to prevent oxidation of the weld.
What are the welding parameters that must be considered to quality weld?
the metals to be welded should be placed correctly, the dust on the metals should be removed, the distance between the metals and electrode should be maintained, proper current must be produced on the basis of metal thickness.
How measure the welding quality with proposenate of material thickness?
proposenately
What is the difference between WPS and PQR?
WPS is welding procedure specification while PQR is procedure qualification records is all about welding and denotes design when it comes to WPS and Mechanical testing of the design when it comes to PQR. WPS is the design of welding joint, process of welding, welding position, steel shape and material symmetry, speed of welding, welding electrodes and filler and many more welding parameters while PQR is a complimentary to WPS. PQR will be the one to be tested mechanically and will finally validate if the WPS viable design of welding.
What are the parameters used in shielded metal arc welding?
Arc length, current (amperage,) travel speed, work angle, travel angle.
Where are some welding schools?
Some welding schools are located in the Midwest. For instance, you will want to consider Heald College, a technical training institute located in California.
