aRather high values of hardness in weld HAZ area from cracked plant components have been observed .The specimen used in the present study also showed significant hardening in the HAZ area, Fig. 3. Fabrication procedures such as surface finishing or grinding can produce a hardened surface [1,3...
How Weld can do more for Mass.David Warsh, Globe Staff
Ideally, people would like to know when an earthquake is going to happen and how bad it will be. Inboth Japan and China, people have long believed that earthquakes can be forecast. In Japan, scientistshave wired the Earth and sea to detect movements. The Chinese have traditionally watched a...
buildingstructures that can withstand the power of earthquakes is a major concern. Steel seems to be the bestmaterial, but not if it is welded to form a rigid structure. Many new structures are built with a new typeof steel joint, an I-joint, which appears to be the most ...

Use good-quality, high-strength, long-cure epoxy (e.g., JB Weld),notel-cheapo 5-minute epoxy from the Dollar Store. LET THE EPOXY COMPLETELY CURE BEFORE MESSING WITH IT! Just walk away from it for a day… (your patience will be rewarded). ...

a one-off weldment will not usually be an ideal candidate for the robotic welder, a one-off project might be. This is because projects are composed of many different weldments. If you have to weld 250 I-beams for example, you might save time by making a jig and programming the robot....
I really did not knew much about structures theory before, even though I weld. I guess that this analysis technique, can too work well to model a composite wing, made of superimposed plies. I have been surprised that the examples of wing box beams on the books, use very basic shapes. ...
