The vertical or horizontal framework to which sash, siding or another finished material is attached is referred as girts.
Gas Metal Arc Welding is a welding method more commonly referred to as GMAW or MIG welding.
Typically used in the automotive and sheet metal industries, GMAW can be an automatic or semi-automatic process. GMAW provides high quality welds at a low cost to the manufacturer.
This arc welding application feeds a GMAW metal consumable electrode and shielding gas through the welding gun. An electrical current travels down the electrode and strikes the arc between the metal being welded and the wire electrode.
3. Explain me what is the SMAW process?
The SMAW process is an arc welding process also known as shielded metal arc welding. It is utilized in welding a variety of materials with an electrode attached to a constant current power source connected to a rod holder. The welding process is one of few where shielding gas is not required.
4. Explain why do you want a career as a Welding Engineer?
A career as a welding engineer is what I have invested my time and energy in to achieve the past 5 years. I enjoy being a valued assest in the manufacturing processes that utilized my welding knowledge and expertise to produce the best product for the customer. With welding being an underappreicate skill and profession, I relish in the opportunities to educate my coworkers on the importance of materials joining and the complexity of the science behind welding.
5. Explain what are the technology used in structural engineering?
☛ Inventory tracking and management software
☛ Cost estimating software
☛ Computer aided design CAD software
☛ Accounting software
6. Tell me what are the essential variables for SMAW process?
In base metal thickness, P-number, dia of pipe, pre, post weld heat treatment
In filler metals F,A-numbers, dia
7. Tell me what is a welding crater?
Unless welding is performed with a very low current, a concave dip, called a crater occurs at the end of a weldment.
This crater results from the force of the arc and the contraction of melted metal when it cools and solidifies. The size of each crater relates directly to the welding current. Craters are not desirable because they cause a welding defect due to slag wrapping.
Crater welding is one method used to fill craters. It requires regular welding current. There are control sequences that allow you to switch to a crater filler current.
8. Explain what was your greatest accomplishment as a Welding Engineer?
Improved the welding process which cut the tack times and cycle times down by 50% that was in time 40 min. Which then increased production and profitability.
9. Explain are welding robots safe to use?
Welding robots are equipped with internal and external safety features. Light curtains, safety stops, walls, weight-sensitive mats, and shielding protect the robot and the robot operator. Other safety features are programmed into the robot. Vision peripherals can also work as safety devices.
Furthermore, welding robots provide a safe alternative to manual welding. Unlike their human counterparts, welding robots don't run the risk of electric shock, severe burns, eye damage, etc.
Instead, they remove workers from the danger zone to the safety of operator's positions. They are oblivious to the bright light, sparks, chemical fumes, and extreme heat caused by welding applications.
10. Tell me what is the Procedure for Fit-Up inspection?
Base metal classification, cleaning, Alignment, root gap, root face, bevel angle & mismatch (or) overlap.
