Welding Signs: Keep Your Worksite Safe
Welding operations come with serious hazards, UV flash, flying sparks, toxic fumes, and fire risk. The right welding signage ensures everyone on site knows the danger before they get close. In this guide, we cover the types of welding signs available, where they’re required, Australian compliance standards, and how to order custom Welding in Progress signs for your worksite.
Why Welding Signs Matter
Welding is one of the most hazardous activities carried out in workshops, factories, and construction sites across Australia. The risks intense UV radiation, flying sparks, toxic fumes, and fire don't just affect the welder. Without proper warning, bystanders, co-workers, and visitors can be seriously injured.
That's where welding signs play a critical role. A clearly visible, well-placed welding sign communicates danger instantly, helps meet workplace health and safety obligations, and protects everyone on site.
What Is a Welding Sign?
A welding sign is a safety sign used to warn people that welding operations are underway or that a welding area is present. The most common type is the Welding in Progress sign, which alerts anyone approaching an area that arc welding, MIG welding, TIG welding, or oxy-fuel cutting is actively taking place.
These signs typically feature:
- Bold, high-contrast text for maximum visibility
- Warning symbols such as the standard hazard triangle or eye protection icon
- UV and weather-resistant materials for indoor and outdoor use
- Compliance with Australian safety signage standards (AS 1319)
Common Types of Welding Signs
Depending on your worksite and the nature of the welding activity, you may need one or more of the following:
- Welding in Progress – The most widely used welding sign, alerting people to active welding operations and the associated hazards of UV flash, sparks, and fumes
- No Entry – Welding in Progress – Restricts access to the welding zone entirely, used when the area must be fully controlled
- Eye Protection Required – Mandatory PPE signage for areas where welding flash or UV exposure is a risk
- Danger – Flammable Materials – Used in conjunction with welding signs where combustible materials are nearby
- Hot Work Area – Indicates areas where heat-generating work including welding is in progress
- Authorised Personnel Only – Limits access to trained and equipped workers in active welding zones
Where Are Welding Signs Required?
Welding signs are required wherever welding or cutting operations take place, including:
- Metal fabrication workshops and factories
- Construction and civil engineering sites
- Mining and resources operations
- Automotive repair and panel beating workshops
- Shipyards and marine engineering facilities
- Maintenance and repair depots
- Educational institutions with trade training facilities
Under Australian WHS legislation, employers have a duty of care to identify hazards and implement appropriate controls, including signage, to protect workers and visitors. Displaying a Welding in Progress sign is a simple, low-cost control measure that forms part of a broader safety management system.
Australian Standards for Welding Safety Signs
In Australia, safety signs including welding signs, should comply with AS 1319: Safety Signs for the Occupational Environment. This standard specifies the design, colour coding, symbols, and placement requirements for workplace safety signs.
Key requirements include:
- Warning signs: Yellow background with black text and border, used for hazards like welding flash and UV radiation
- Danger signs: Red, black, and white, used for immediate life-threatening hazards
- Mandatory signs: Blue background with white symbol, used for PPE requirements such as eye protection
- Prohibition signs: White with red circle and diagonal bar, used for no-entry or no-access zones
Our welding signs are designed to meet these standards, ensuring your workplace remains compliant and your team stays protected.
Materials & Durability
Welding environments are tough, your signs need to be tougher. We offer welding signs in a range of materials to suit different applications:
- Corflute (5mm): Lightweight and cost-effective, ideal for temporary welding zones or short-term projects
- Aluminium composite: Rigid, durable, and suitable for permanent indoor or outdoor installation
- Self-adhesive vinyl: Easy to apply to walls, doors, and equipment; suitable for indoor use
All materials are printed with UV-resistant inks to ensure colours remain vivid and legible over time, even in harsh Australian conditions.
Custom Welding Signs
Standard welding signs cover most situations, but sometimes you need something more specific. We offer fully custom welding signs that can include:
- Your company name or logo
- Site-specific instructions or contact details
- Custom sizing to suit your location
- Bilingual text for multilingual worksites
- Non-standard symbols or combined hazard messaging
Whether you need a single custom sign or a bulk order for a large facility, our in-house design team can turn around your order quickly with Australia-wide delivery.

FAQ's
Q. What does a Welding in Progress sign mean?
A Welding in Progress sign indicates that active welding operations are underway in the area. It warns bystanders and workers of hazards including UV radiation (welding flash), flying sparks, heat, and toxic fumes. Anyone entering the area should wear appropriate PPE.
Q. Are welding signs a legal requirement in Australia?
Under Australian WHS legislation and the duty of care obligations it imposes, employers must identify and control workplace hazards. Displaying appropriate safety signage, including welding signs, is a recognised control measure. While specific sign requirements vary by state and industry, failing to display adequate warnings can constitute a breach of WHS obligations.
Q. What size should a welding sign be?
Sign size depends on the viewing distance. As a general rule, the sign should be large enough to be clearly read from the furthest point at which a person could approach the hazard.
Q. Can I get a custom Welding in Progress sign with my company logo?
Yes. We offer fully custom welding signs that can include your company name, logo, site-specific instructions, and custom sizing. Contact us for a quote.
Q. What material is best for welding signs in a workshop?
For permanent workshop installations, aluminium composite panel signs are the most durable option. For temporary or short-term welding zones, 5mm corflute signs offer a cost-effective solution that's easy to move and reposition.
