The valuesstated in each system are not exact equivalents; therefore eachsystem must be used independently of the other. SI valuescannot be m

Othermethods of welding, such as the addition of filler metal or handwelding, may be employed if approved by the purchaser andtested by methods agreed upon between the manufacturer andthe purchaser. If filler wire is used, it must meet the chemicalrequirements of the appropriate grade as sh
