The ultimate shear capacity of arc spot welding is formulated in terms of tensile strength, average welding thickness and diameter.
The results showed that the weld spacing and nugget diameter were polynomial-correlated, and the minimum welding spacing of 20 mm can be derived from the results.
Welding parameters of laser power, welding speed and wire feed rate were carefully selected with the objective of producing a weld joint with the minimum weld bead width and the fusion zone area.
Through the optimization process, the desired weld bead with good integrity and minimum weld area are obtained and the corresponding microstructure and microhardness are excellent.
The conventional approach of obtaining shop-floor applicable welding conditions considering maximum penetration, minimum weld width, minimum dilution, etc. are difficult to simultaneously achieve or if accidently achieved are not necessarily be sustainable and practically applicable.
In all cases minimum tube thickness is desirable.
The minimum film thickness was less than 3 nm.
At present, a minimum coating thickness of 40 μm is required to determine the coating thickness.
The minimum deck thickness includes a 1 inch wearing surface.
The estimated value of minimum chip thickness is obtained.
