Cold repairs and restarts of photovoltaic glass lines are clustered, and the inspection and restocking of electric boosting molybdenum electrodes are being moved ahead of ignition. The article reviews cold repair schedules, electrode inspection checkpoints and points to watch during the restart ramp-up.

Spent electrodes are often stacked temporarily after an electrode change, which invites secondary impact damage and mixing of grades. This article describes how to set up a holding area, stack electrodes by condition and keep handover records, so that later sorting and recycling link up smoothly and material does not pile up on site.

This article introduces the matching logic for molybdenum and molybdenum-copper materials in electronic packaging, heat-spreading substrates and heat sinks, analyzes how the coefficient of thermal expansion, thermal conductivity and layered structure design affect reliability, discusses the key points of plating and joining processes, and provides a verification checklist covering thermal cycling, thermal resistance and batch consistency for design and process engineers.

Building on its pure molybdenum electrode line, WeiBeam has added lanthanum-doped molybdenum electrodes and TZM (titanium-zirconium-molybdenum) alloy electrodes, aimed at duties that demand higher high-temperature strength and longer replacement cycles. Together with the existing specially processed pure molybdenum electrodes they form a complete portfolio from routine electric boosting to demanding full electric melting, with standard-size samples (1-2 pieces per company, freight collect).

A comparison of molybdenum, tungsten and alumina thermocouple protection tubes for vacuum, inert atmosphere and melt service. It explains that the temperature limit, corrosion resistance and response speed must be weighed together, sets out the trade-offs in wall thickness, insertion depth and installation sealing, and lists the process information and inspection items to confirm before selection; process confirmation should be recorded in writing.

The requirements of ultra-clear rolled glass and electronic glass for iron content, transmittance and forehearth temperature uniformity determine electrode layout and material limits. This article analyzes the thermal shock losses caused by low-load operation and the packaged procurement logic within the cold-repair window, as a reference for cold-repair scheduling.

Glass thermal bending and forming molds set requirements for heat resistance, wear resistance and thermal conductivity. This article explains where molybdenum alloys fit in inserts, guide components and localized load-bearing surfaces, compares the roles of graphite, heat-resistant steel and molybdenum alloys, and gives guidance on selecting materials by part, surface maintenance and wear records. Material assignments by part should be written into the process documents.

Quartz melting temperatures approach 2,000°C and usually take place under hydrogen or vacuum, so the purity and surface condition of molybdenum components feed directly into product specifications.

In 2026, WeiBeam's quality traceability system went live, linking data across the entire molybdenum electrode flow from raw material batch, forming and sintering through to machining and outgoing inspection, so customers can query the production and test records behind the code supplied with each shipment.

Insertion depth changes more than the contact area: it also changes the current path and the convection loop in the glass melt. This article explains how changes in depth affect current density, flow pattern and electrode temperature, gives the basis for deciding whether to adjust the depth and the parameters to monitor continuously after an adjustment, and points out common misconceptions such as treating depth as a temperature switch.
