Chapter 10, Problem 1R
Why is usage of the term GWW preferable to MIG for gas metal arc welding?
Expert Solution & Answer
To determine
Reason of using the term GMAW over MIG for gas metal arc welding.
Answer to Problem 1R
GMAW is preferred over MIG for gas metal arc welding as other gases apart from argon are used in metal arc welding.
Explanation of Solution
The term MIG stands for Metal inert gas welding, an inert gas is used to protect the weld from impurity. Initially, Argon as an inert gas was used forshielding.
Later, after developments in the technology associated with welding, carbon dioxide
Argon was used for shielding the weld. It was termed as MIG welding and was named as Gas Metal Arc Welding (GMAW) by American Welding society because other gases can also be used for shielding.

Q is the internal heat source, which heat is generated per unit time per unit
volume. q(x) and q(x + dx) are the heat flux conducted into the control
volume at x and x + dx, respectively. k is thermal conductivity along the x
direction, A is the cross-section area perpendicular to heat flux q(x). T is the
temperature, and is the temperature gradient.

- A pipeline engineer is considering alternative natural gas pipeline routings. The first route is mostly over land and the second is primarily undersea. Both pipelines will need some valve and fitting replacements in year 25. Cost data for each route is shown in Table P2.21. Notice that the undersea route has a higher initial cost due to higher installation costs and extra corrosion protection for the pipeline. However, the undersea route has cheaper security and maintenance costs which substantially reduces annual costs. The MARR for the project is 15%. Determine which route should be pursued based on a present worth analysis.arrow_forwardThe state of stress at a point is σ = -4.00 kpsi, σy Tyz = 8.000 kpsi, and T₂ = -14.00 kpsi.
