ASTM A307

The ASTM A307 specification covers carbon steel bolts and studs ranging from 1/4″ through 4″ diameter. This is your everyday, run of the mill bolt specification often manufactured using A36 round bar. There are three grades A, B, and C* which denote tensile strength, configuration, and application. Refer to the Mechanical Properties Chart for the subtle strength differences within each grade.

A307 Grades

A	Headed bolts, threaded rods and bent bolts intended for general applications.
B	Heavy hex bolts and studs intended for flanged joints in piping systems with cast iron flanges.
C*	Nonheaded anchor bolts, either bent or straight, intended for structural anchorage purposes. The end of a grade C anchor bolt intended to project from the concrete will be painted green for identification purposes. Permanent marking is a supplemental requirement. *As of August 2007, grade C has been replaced by specification F1554 grade 36. We will continue to supply grade C, if required by the project.

How would you feel with that, Andrew?”

Here is a step-by-step tutorial on how to make an 800 amp Spot Welder from common materials and for dirt cheap! Spot welders are used to fuse thin sheets of metal together and can cost hundreds of dollars to buy. In this video, we’ll do it for practically nothing!

Project History & More Info:

By modifying the secondary coil on a MOT, the transformer is converted from a high voltage/low current device into a low voltage/high current metal melter. High current can be directed to one focused location to fuse sheets of metal together on contact.

Using some scavenged parts from the microwave in a previous project, as well as some wood panels and a few other accessories, we can make a fully functional Spot Welder that works well, and has some built in safety precautions!

The electrical power is high enough to turn a nail into boiling liquid iron.
