(PDF) WELDING INSPECTION -STEELS CONTENTS

Steels with carbon contents between 0.15% and 0.25% are preferred for welding, as they rarely present weldability problems if the impurity levels are kept low. The steels with carbon levels higher than 0.25% can be susceptible to cracking if other hardening elements like 1983 Ford Ranger Truck HSLA Steel Wheelheat treatment can result in potential savings, but is partially offset by the cost of the Fig. 3 - 750X, nital etch.
