The Welder Sub Download [EXCLUSIVE]
The constant current power system is normally used for welding with 5/3 2 in. (4 mm) and larger-diameter electrode wires. The control circuit for CC power is more complex since it attempts to duplicate the actions of the welder to retain a specific arc length. The wire feed system must sense the voltage across the arc and feed the electrode wire into the arc to maintain this voltage. As conditions change, the wire feed must slow down or speed up to maintain the prefixed voltage across the arc. This adds complexity to the control system. The system cannot react instantaneously. Arc starting is more complicated with the constant current system since it requires the use of a reversing system to strike the arc, retract, and then maintain the preset arc voltage.

Several problems may occur when using the semiautomatic application method. The electrode wire may be curved when it leaves the nozzle of the welding gun. This curvature can cause the arc to be struck in a location not expected by the welder. When welding in fairly deep grooves, the curvature may cause the arc to be against one side of the weld joint rather than at the root. This will cause incomplete root fusion. Flux will be trapped at the root of the weld. Another problem with semiautomatic welding is that of completely filling the weld groove or maintaining exact size, since the weld is hidden and cannot be observed while it is being made. This requires making an extra pass. In some cases, too much weld is deposited. Variations in root opening affect the travel speed. If travel speed is uniform, the weld may be under- or overfilled in different areas. High operator skill will overcome this problem.
This is the Weld.com podcast, where we feature all of the talent that our community has to offer. As a global hub of resources for the welding community, we highlight not only welders, but sculptors, artists, machinists, instructors, CWI's, engineers and more.
"Weld.com is by far the best welding education site I have seen. Some of the others are more geared toward "Look what I can do". Weld.com is more "Here is how you do it". I have been in the welding industry for 31 years and the last 16 years in welding education, I am also a CWI/CWE. The information welders of all levels can get from their videos and social media platforms is top notch information."
Just wanted to say thanks for the quality content. I watched your youtube videos to help me decide which welder to get, I went with an esab 205 emp ac/dc. I'm a heavy equipment mechanic in a mine and need to improve on my welding skills. Your videos are a wealth of knowledge for guys like me.
The American Welding Society's Board of Directors recently authorized free electronic distribution of the current ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes. The Board decided this important voluntary welding safety and health standards document should receive the widest distribution possible and has directed that Z49.1:2021 be made available for free download.
The 2021 revision is now available and accessible for free download from the AWS website. During the period of these revisions, the American Standards Association has become the American National Standards Institute and War Standard ASA Z49.1-1944 has become ANSI Z49.1:2021.
This application can be deployed on the factory floor using the Edge Insights for Industrial software package. A sample implementation can be downloaded by selecting the Weld Porosity Detection Application under Video Ingestion & Analytics (Step 3 of 6) tab from the Customize & Download section on the bottom-right.
This study revealed that the level of awareness of occupational hazards among welders was high. However, this does not mean that there will be no need for further strengthening of the safety measures as significant proportions of the workers still had low awareness. Interventions to boost workers awareness of occupational hazards should focus on areas, such as provision of safety trainings, promotion of safety advocacy, and enforcement of appropriate workplace safety regulation.
Industrial safety and health problems are becoming major challenges in Ethiopia because of low occupational hazards awareness, lack of workplace safety and health policy, and inefficient safety management system. Due to these employers, workers and the government are losing measurable costs. There is an information gap on occupational hazards in welding industries in the country. Therefore, the aim of this research is to assess the level of awareness of occupational hazards and associated factors among welders at Lideta Sub-City, Addis Ababa, Ethiopia. Such information is vital in understanding the extent of the problem and may be useful when designing intervention strategies targeted at promoting and upholding good health and safety standards in this important working group.
A work site-based cross-sectional study was conducted to assess level of awareness and factors associated with occupational hazards among welders at Lideta Sub-City, Addis Abba, the capital city of Ethiopia, from April to May 2015.
The CSA Standard W117.2 states that contact lenses should not be worn by welders and welding personnel because foreign bodies (objects) in the eye can cause excessive irritation. Contact lenses do not provide protection from ultraviolet radiation and flying objects. All workers in proximity to welding procedures must wear appropriate eye protection according to the circumstances. The OSH Answers document Contact Lenses at Work discusses how dust particles or chemicals can irritate the eyes.

Although there are a great many advantages, there are some drawbacks with this process. This type of welding produces more waste than other methods, meaning that project costs can be higher for some jobs. This process also requires a high level of skill and training for arc welders, while it can also be difficult to join thin materials using arc processes.
All other rules as it relates to welder continuity submissions remain; i.e., even if the 120-day rule is met, the continuity date must be before the most recent expiration date for the given record (process type).
The welding industry requires wearing appropriate PPE when performing weld. It helps protect welders from the unnecessary incident including skin burns, blindness, or overexposure to fumes and gases. The following welding safety equipment list can protect welders from welding hazards.
