I guess there are many Engineers and technicians are looking forward to learn about Latest Welding technology. There has been quite number of Mechanical Design Engineers seeking Welding tutorials to know about Welding Techniques.
Even there are many institutions offer welding courses and become a certified welder, many people rely on Internet to get welding books and study materials. Many industries require Certified and experienced welders in Gulf and European countries. If your are looking job opening in Welding Field, check out this
Immediate Opening - MIG Welder Position (Lakewood, WA)
American Welding Society Jobs portal
This time I would like to show good Welding education resource. Gas welding,Arc welding,MIG,TIG are quite familiar welding types Laser welding,Ultrasonic welding are hot topics now a days. Underwater welding and plastic welding are emerging techniques.
In this session you can learn about best practices, Do's and Don't's,Welding failures,How to strength welding joint and many more..
Welding
How To Prevent Weld Failure :- Common causes of weld failure and how they can be avoided.
Calculating the strength of welded connections :- Design Rules for calculating the strength of butt and fillet welded joints subject to Direct, Bending and Torsional loadings. Plus guidance on calculating centroids and second moment of area.
Welding Procedures and WPS's :- Welding procedure and welder approval qualifications to European, ASME and the new EN ISO Standards explained. Plus how to draft welding procedure specifications
Fatigue Of Welded Joints :- A practical guide to Fatigue in welded structures.
Fracture Mechanics : - Basic guide to fracture mechanics and fitness for purpose assessment + ASME Impact requirements
Preheat:- How to reduce the risk of hydrogen cracking in carbon and low alloy steels. + Preheat calculator.
Welding Metallurgy :-Practical information on the welding and treatment of:- stainless steel, duplex. More materials to be added shortly. + Welding dissimilar materials and welding without PWHT.
Welding Symbols :- A brief guide to welding symbols to EN22553, BS499 and AWS.
Pressure Vessel Design
Pressure vessel design to both American (ASME 8) and European codes (EN13445).
Finite Element Analysis:-A basic guide to solving structural and heat transfer problems using matrix methods + Free Beam Calculation Software
A basic introduction into stress/strain relationships & weld design.
Formula for calculating the stresses in a fillet weld.
Formula for calculating the stresses in lap fillet welds subject to shear.
Fillet welded cantilever subject to bending and shear
Fillet welded lap subject to Torsion and shear
Rectangular Block Subject To Torsion
Rectangular and fillet welded and subject to Torsion
T Butt Weld Subject To Torsion
Full Penetration T Butt welded Cantilever subject to Torsion
Lap Joint Subject To Bending and Shear
This calculation method is one I came up with. Unfortunately I couldn't find a similar joint in any technical reference to verify it.
Welding Qualification and Certification importance:
An introduction to European Welding Standards. (427Kb pdf File)
A basic introduction to Welding qualifications and why they are required
Welding Procedure Specifications(WPS)
Welding Procedure Specifications to EN ISO 15609-1 (formerly EN288 Part 2). Why are they required and what should they include.
Guidance on the qualification of welding procedures and the performance testing of welders to section 9 of the ASME boiler and pressure vessel code. Approval Range Calculator.
European & ISO Welding Standards
These new standards are renumbered and updated versions of the old EN288 series. Information is also provided about the older standards.
NEW Approval Range Calculator.
Guidance on the qualification of welding operators to EN and ASME Rules
Independant Inspection Authority
Royal & SunAlliance is probably one of the most helpful Inspection agencies around.
My personnel thanks to Mr.John Dyson who is registered European Welding engineer(gowelding.com) has put lot of effort to prepare this welding Tutorial and sharing his experience with other welding engineers on net.
