Where crack repair makes sense
Crack repair is suited to parts where accuracy still matters and replacement would cost far more than repair. We work on worn or stressed components from manufacturing, tooling, maintenance and light engineering, especially where the crack is small but the part itself is valuable. Common work includes mould sections, dies, brackets, housings, shafts, fixtures, frames and fine mechanical parts.
Because the heat affected zone is kept tight, laser repair is often a better option than broad arc welding on thin sections or close tolerance edges. It helps reduce distortion, which is important on parts that must still fit, seal or align after repair. This is especially useful for clients in Centurion, Pretoria East, Rosslyn, Midrand and Jet Park, where turnaround pressure is often tied to plant downtime.
- Small, localised cracks on precision parts
- Thin section components that cannot tolerate heavy heat
- Parts needing dimensional control after repair
- Items where replacement lead times are long or costly
What is included in the repair service
Our crack repair service includes inspection, crack tracing, surface prep, laser build-up where needed, blending and a final check before release. If the part needs machining after welding, we can advise on the best sequence so the finished size stays within tolerance. For urgent breakdown work, we can also handle collection through our Midrand collections point or arrange a courier job from anywhere in South Africa.
We focus on repairs that are practical and measurable. If the crack runs into a stressed corner or a worn edge, we can build and shape the area back up rather than simply closing the split. That is useful on tooling and production parts where a straight weld bead would not last long. Our workshop in Centurion is set up for small batch work as well as single items, so jobs can be grouped when needed.
- Initial inspection and repair advice
- Laser welding on localised cracks
- Edge build up if material loss is present
- Basic blending and tidy finish
- Quality check before collection or dispatch
How we handle the repair from start to finish
Every job starts with identifying the crack length, depth and cause. We then clean the area, remove contamination and set up the part so the weld is placed only where it is needed. The laser process allows fine control over energy input, which is useful on stainless, aluminium and mixed repair work where heat control matters. The operator can work in short passes, checking progress as the material responds.
After welding, the repair is examined for continuity and surface condition. If the job needs further machining, polishing or fitting, we can flag that early so there are no surprises later on. In many cases the part can be turned around without long cooling delays, which helps when a production line or maintenance shutdown has a tight window. Load-shedding can affect many workshops, so we plan jobs carefully to keep work moving where possible.
Turnaround times and job sizing
Turnaround depends on crack size, material type and whether the part is ready for repair when it arrives. Small crack repairs can often be completed quickly, while larger or repeated cracks may need a more measured approach. Single parts are welcome, and so are batch jobs where several items from one plant or production run come in together.
For local clients in Pretoria and Centurion, faster turnaround is often possible when parts are dropped off in person. National clients can send parts by courier and receive updates from our team before and after repair. If the component is sensitive or expensive, we recommend packaging it well and including any drawings, sample parts or tolerance notes. That helps us work accurately and avoid back-and-forth delays.
- Small local repairs: often same day or next working day
- Medium repairs: usually a short workshop turnaround
- Batch repairs: scheduled to suit job volume and urgency
- Courier jobs: timing depends on collection and delivery
Pricing based on the part, not a flat guess
Pricing is based on the actual work involved, not on a one-size-fits-all rate. We look at material type, crack length, access, thickness, prep needed and whether the repair must be built up or only sealed. This keeps pricing fair for both small precision items and larger workshop components. If a part is difficult to hold or needs careful handling, that is considered in the quote as well.
For repeat work, batch quantities and planned maintenance repairs, we can quote in a way that suits ongoing production. That helps maintenance teams and manufacturers budget better and reduces surprise costs when a crack shows up during shutdown. We keep communication direct, so you know what is being repaired, what is included and where any extra machining or finishing may be needed.
Keeping repaired parts in service for longer
A crack repair should not only hold for the short term, it should make sense in service. After repair, the part should be checked at suitable intervals, especially if it lives in vibration, heat, chemical exposure or repeated loading. In coastal conditions, stainless and other metal parts may still need regular inspection because humidity and salt exposure can open up weak points over time.
For plant and workshop items, we usually advise aligning inspections with planned maintenance stops. On high-stress parts, that may mean a visual check every 3 to 6 months, with earlier attention if the part starts showing staining, movement or fine surface lines. If a crack reappears, the cause may be fatigue, poor fit or overload, not just the weld itself. Fixing the root issue matters as much as the repair.
- Check repaired areas during routine maintenance
- Watch for repeat cracking near corners or holes
- Keep parts clean and dry where possible
- Report any new movement or distortion early
