Establishing a list of hazardous jobs that call for safe work permits, putting the necessary permit systems in place, and maintaining them.
Safety Concerns Particular to Arc Welding
The welding area must be shielded from bystanders’ eyes. Since thick metal is typically used for arc welding at high amps, the arc’s light output is exceptionally bright. Welding techniques slag can ping off a hot weld and get into the eyes, hence overalls and welding gauntlets (gloves) shall be used. Any exposed skin will become burnt quickly.
Use of safety glasses or goggles is required. Arc welding of stainless steel requires the use of a fume mask. Keep a fire extinguisher nearby; dry powder and CO2 extinguishers are both acceptable.
Foam or water-containing products should never be used close to electrical equipment that is powered by the mains. Slag can go a fair distance because it is fragile and light. When chipping, eye protection is need to be worn.
Welding Techniques
Methodology
The materials delivered to the site must undergo a thorough inspection by a QA/QC engineer and must be stored correctly in accordance with manufacturer requirements. According to the ITP, the Inspection of Delivered Materials shall be enhanced. The site staff, including the engineer, supervisor, and foremen, must complete the work properly and under close supervision.
The Arc Welding Checklist must be followed by the QA/QC Inspector while inspecting every welding.
According to ITP, the QA/QC Inspector must submit a request for inspection to the consultant for review and approval.
Arc Welding Inspection Fit up and Preparation
Cleaning of Base Metal
To avoid the production of oxides, cleaning should be done right prior to welding. The surface of the base metal must be free of any contaminants, including grease, oil, paint, and dirt. A smoother, stronger joint will be produced by a clean surface. To get rid of burrs and oxides, use a stainless steel wire brush to brush the plate’s surface and edges. To avoid hand oil or dirt getting on the connecting surface, gloves should be worn.
Fit up Inspection
Prior to carrying out the fit-up and final visual inspection required inspection, which may cover any or all of the following components, the QC Inspector assigned reviews the WIR and the specific requirements of the drawings, Welding Procedure Specifications (WPS), and appropriate operating instructions.
Joint placement in accordance with the approved shop drawing. Cleanliness of the fusion face, alignment (Hi-Lo), fit up inspection for welding materials, accurate grade and rating / schedule, temporary attachments / tacking adequacy Joined parts are square, plumb, or level. Weld preparation in accordance with the approved WPS.
Weld identification Welding procedure qualification Identification of the WPS to be used. Adequate protection from unfavorable weather conditions. In accordance with the drawing identification tags, tacky welds. Correct and current welder qualification.
Procedure Qualification for Welding
After approval, the Project QC Inspector will specify the necessary activities, sign the WIR, and deliver the copy of the fit-up request to the production supervision with the notation that it has been approved. The Project QC Document Controller will get the original of the fit-up request and welding procedure qualification.
Initial Cleaning
The surface needs to be free of organic contaminants.
Techniques for Welding (Procedure)
The “Tap Starting” and “Scratch Starting Methods” are used to initiate the arc by briefly tapping the electrode against the work to complete the electrical circuit before elevating the electrode to create the arc.
The rod should be dragged in the direction of the arrow and tilted 10 to 20 degrees from vertical for welding on the flat surface (see below photo).
The distance between the electrode and the weld pool is known as the arc length. It ought to be nearly equal to the rod’s diameter. Over the course of the weld, the proper arc length must be maintained. The flaws in the photo below are the result of incorrect arc lengths.
To create a “stringer,” the rod is moved straight ahead while welding. Arc welding needs to be done correctly and quickly to avoid weld flaws.
Three layers of arc welding must be used on structural steel. There is a first root weld made (1). A single stringer with a light weave is made to make half of the weld (2) after the root weld (1) is cleaned up, and a second stringer is utilized to complete the weld (3).
After welding, the area must be ground clear of any slag.
Here are some fundamental welding pointers:
Fixtures and/or jigs can be used to hold work in place. The edges that touch should be squared. Structure plates frequently have a fillet weld junction. The edge of heavier, thicker plates might need to be beveled to ensure complete penetration. The weld puddle should be dipped into, not dripped into, using the electrode welding method of statement. To keep consistency, move the electrode along the joint at a steady, continuous speed. To safeguard the work, hold the electrode over the weld.
Access and exit
The contractor will provide assembled scaffolding with a step ladder attached and rubberized wheels. In situations when scaffold assembly is prohibited at the workplace and for installation alignment, aluminum ladders will be used. Before using ladders or scaffolding, they should be prepared and approved by safety personnel.
Lighting
The contractor will appoint a certified electrician who will report to the site engineer, as well as appropriate lighting for the workspace areas. Safety personnel must be the activity’s supervisor, distribute the illumination, and check any wire installations.
Equipment and Tools
During structure welding, the following tools & equipment will be utilized:
Toolbox with a calibrated welding machine, a potable oven, an electrode measuring tape, welding gloves, a welding mask, and a wire brush grinder.
Materials
All materials supplied to the site will first be examined by the store in charge I site in order to check that they are in accordance with the site requirement, the approved submittal, and the material qualification, as well as that they are free of any damage from the delivery process.
Check for completeness in the delivery documents.
Defective or damaged materials must either be stored on site in an appropriate quarantine area or returned to their supplier’s facility. The site will be cleared of these damaged materials. It should be emphasized that the materials utilized in this work are of a valuable nature and that access to them must be tightly regulated. They must also be stored in a secure location.
Technician Competency
The site team work (engineers, supervisors, foremen, and welders) must be qualified, experienced, and competent to carry out their tasks as needed.
Emergency Planning
Once the Safety Officer/1st Aider has completed their inquiry and informed the appropriate parties, they are then responsible for checking the person in case of an accident or illness and transferring them to the clinic.
Housekeeping
The Supervisor is responsible for instructing his employees to clear the site of any debris, collect it, and then separate the debris into used and unused materials, which will be placed in disposal boxes.
Quality Control/Quality Assurance
The QC Engineer/Inspector is responsible for monitoring and supervising the work activities to ensure that they are carried out in accordance with this method statement. If he discovers any mistakes, he must instruct the supervisor to repair them in accordance with the standards of workmanship.
Environment-Related Issues
According to site and authority regulations, the trash from those projects will be divided up and disposed of. To prevent spills on the floor, the chemical or cleaning used for the work should be stored in a separate container
