| Lessons from the Shipyard |
|
Welding Engineering Supplier Support, a collaborative effort between Welding Engineering Supplier Development and Supplier Oversight, has release Supplier Welding Bulletins (SWB), to the supply base detailling various lessons
learned from on-site welding activities.

Topic |
| SWB-0042 |
Stop Resisting! |
Wire feed issues can be caused by multiple factors and may require replacing a part in the system. |
| SWB-0041 |
Welder Qualification Contemplation |
Routine process use & passing your exams are part of maintaining your qualifications. |
| SWB-0040 |
Don't Just Eyeball It |
When in doubt ask about what thickness to base preheat on. |
| SWB-0039 |
Bright Lights |
Arc welding poses hazards to your eyes. Always be sure to take precautions to protect them. |
| SWB-0038 |
Level I Lockup |
Level I weld wire must be segregated in a locked enclosure to ensure proper quality control. |
| SWB-0037 |
Can I Color Inside the Lines? |
Temperature measuring devices other than temp sticks are allowed to be used on weld metal or in the weld joint. |
| SWB-0036 |
Round and Round It Goes |
Good cable management can prevent damage and hazards. |
| SWB-0035 |
What's in a Name? |
Material types are chosen for a specific reason, and will not perform as intended if the wrong material is used. |
| SWB-0034 |
All the Nooks and Craters |
Remember to clean all the nooks and craters during interpass cleaning. |
| SWB-0033 |
Get to the Point |
A clean and properly sharpened tungsten will limit weld imperfections and contamination. |
| SWB-0032 |
Mirror, mirror on the Weld |
Over processing the weld for NDT prep can negatively impact the weld. |
| SWB-0031 |
No Decoder Ring Necessary |
Ensure joint preparation, dimensions, and welding are in accordance with all design-specific requirements. |
| SWB-0030 |
A Flow State of Mind |
Think about what size gas cup will optimally cover your joint and read your flowmeter correctly. |
| SWB-0029 |
Where's the label? |
Always read the bottle tag before use and confirm with the welding procedure before using any gas canister. |
| SWB-0028 |
Don't Explode (Gas Bottles) |
Bottle safety is extremely important: damaged equipment can result in poor welds and accidents. |
| SWB-0027 |
Based on What? |
Verify that your studs match what is specified on the stud welding procedure. |
| SWB-0026 |
How Did That Get In There? |
Tungsten inclusions are detrimental to welds and need to be removed if they occur. |
| SWB-0025 |
Not Going Anywhere |
Securing work pieces in place prevents potential damage and reduces the risk of injury. |
| SWB-0024 |
Really Cooked That One |
Heat input is a critical element of welding and must be verified prior to welding. |
| SWB-0023 |
Not That One |
Cross contamination of materials can be prevented by control of surface prep materials. |
| SWB-0022 |
Littering and ... |
Proper disposal of filler materials is an important step at the end of a job. |
| SWB-0021 |
Don't Believe It |
Weld profiling before inspection helps reduce false MT indications. |
| SWB-0020 |
I lost It |
Loss of preheat events must be evaluated based on the materials used before proceeding. |
| SWB-0019 |
A Little Off the Top |
Clipping the end of filler wire is a good habit for a quality weld. |
| SWB-0018 |
Mind the Gap |
Double check welder performance qualifications before welding. |
| SWB-0017 |
Coloring Outside the Lines |
Temperature indicating crayons are not to be used on weld metal or in the weld joint. |
| SWB-0016 |
Don't Fall Down |
Downhill welding is typically prohibited for its potential complications. |
| SWB-0015 |
You Can Eat Off It |
Base material cleanliness is the start of producing a sound weld. |
| SWB-0014 |
You Call That a Weld? |
Tack welds have fabrication requirements just like full welds. |
| SWB-0013 |
We Don't Need No WPS |
Follow your WPS for all welding parameters/ranges defined. |
| SWB-0012 |
Let It Flow |
Ensuring a proper welding circuit is set up before welding. |
| SWB-0011 |
I'm Late, I'm Late |
Time limits for SMAW elecrodes are integral for hydrogen control in weld metal. |
| SWB-0010 |
What Goes Where? |
Filler material control procedures/programs are critical to maintain weld integrity and quality. |
| SWB-0009 |
Don't Be Shocked |
Checking equipment for electrical hazards avoids unsafe working conditions. |
| SWB-0008 |
Where Did It Go? |
Copper loss from contact tips and gas cups is an indication of weld quality issues. |
| SWB-0007 |
