Project Zomboid Metalworking Guide: How the Welding Skill Really Works

 

    Project Zomboid doesn't actually have a skill called "Metalworking" — the skill governing metal barricades, walls, and scrap-metal crafting is named Welding in-game (skill ID MetalWelding), and that's the name pzwiki.net's page uses throughout, so this guide sticks to it too. The in-game tooltip describes it plainly: "Allows the building of crude metal barricades and objects." One accuracy note before anything else: pzwiki.net itself flags that this page "was last updated for an older version of the current build (42.18.0). The current stable version is 42.20.4, so information on this page may be inaccurate" — worth keeping in mind if a number here doesn't match your current install.

 

What Welding Actually Does

 

    Per the wiki's infobox, Welding is a Crafting-type skill that "Modifies" Build speed and health. The overview section is direct about the scope: "Welding allows a player to barricade windows and doors with metal, craft metal structures and containers, repair car parts, and disassemble metal objects in the world."

 

    Leveling up isn't cosmetic. The Effects section states "Higher levels allow crafting better items and gives more HP to the constructions," and ties that directly to wall/window tiers: a level-1 wall or window requires Welding 2, while a level-2 wall or window requires Welding 8. The source adds two more specifics worth quoting exactly: "Walls/windows of level 1 can be upgraded to the next higher level after building," and "The health of a wall is directly affected by the welding level."

 

 

Fastest Ways to Level Welding

 

    The wiki lists specific "most efficient actions" per level range, and the numbers are worth doing the arithmetic on rather than just reading flat:

 

• Level 1-2 — dismantling car wrecks, "about 17 XP per 10 Welding Torch Uses." That works out to roughly 1.7 XP per torch use.
• Level 3-4 — crafting a scrap metal knife, "20 XP per 4 Welding Torch Uses," or 5 XP per use — about three times the rate of car-wreck dismantling.
• Level 2-4 (alternative) — cutting a bar, "10 XP per 1 Welding Torch Uses," a strong per-use rate (the metal-sheet method below edges it out at 12.5 XP per use), with the note that "bars can be reforged with a Simple or better Forge and Charcoal."
• Level 5-10 — making a metal sheet or cutting it into 4 small metal sheets, "25 XP per 2 Welding Torch Uses for both recipes," or 12.5 XP per use.

 

    The source also flags a version change worth knowing: "In Build 41 the skill was increased by dismantling various metal objects and furniture. That is no longer the case in Build 42 (except car wrecks), unless specified in sandbox settings." Disassembly itself is a gamble at low skill — the wiki lists three possible outcomes when taking an object apart with a propane torch and welding mask: "Regular materials + scrap metal will be awarded," "Only scrap metal will be awarded (partial failure)," or "No items will be awarded (total failure)." The wiki's own list of takeable objects is explicitly partial ("Below is a list of some of the objects that can be taken apart"), so no total count is given and none is invented here.

 

    Entertainment also grants Welding XP, capped to "the first 3 levels and any overflowing XP amount." Specific VHS tapes named on the page: Adefope Fencing Special (+112.5), Home Welding Guide (+75), Z-Squad S2.03 (+12.5), no 9 (+112.5), and nof vid (+100).

 

 

Occupations, Traits, and Skill Books

 

    Two occupations affect your starting Welding level, per the source: Welder starts "+4, knows the recipes," and Mechanic starts "+1." Three traits affect the XP rate instead, with "no effect on starting level": Crafty and Fast Learner each "increase the XP rate to 130%," while Slow Learner "lowers the XP rate to 70%."

 

    Skill books stack on top of that. The wiki lists five, each covering two levels, with their exact in-game titles: Welding I "Basics of Welding" (Levels 1-2), Welding II "Building with Metal" (Levels 3-4), Welding III "Machining Metal: The Mass Genfac Guide" (Levels 5-6), Welding IV "Ore to Sheets: A Complete Metalworking Manual" (Levels 7-8), and Welding V "Technological Fundamentals of Metal Fabrication" (Levels 9-10). Separately, recipe magazines unlock specific crafting recipes rather than boosting XP — the wiki names 15 of them (four Welder Monthly issues, three Everyday Smithing issues, Small-Scale Smithing, Blunt Forge, Modern Blacksmithing at Home, two Medieval Armory issues, American Bladecraft, Iron Age Blacksmithing, and Medieval Blacksmithing).

 

 

Quick tips from the source data: A propane torch and welding mask are required for both construction and disassembly, and welding rods are additionally required to build anything — a propane tank refills a torch's fuel. Materials worth stockpiling: Steel Sheet, Steel Sheet - Small, Steel Rod, Iron Pipe, Scrap Metal, and Wire. Multi-stage builds like metal walls and windows start as a wall frame (buildable on a wooden or metal frame) — the wiki notes "zombies can climb through wall frames" until you finish them, so don't leave one half-built overnight. Metal doors are the exception: they "cannot be built this way and must be built using a wooden door frame" instead.

 

Running your own Project Zomboid server

 

    Grinding Welding solo means racing the clock between car-wreck runs and the disassembly RNG at low skill — a dedicated server with friends splits that workload, so someone's always stockpiling Scrap Metal while someone else holds the torch. Get your own Project Zomboid server running in minutes, with support for the traits, occupations, and sandbox settings covered above, and save on your first month with code WELCOME.

 

Conclusion

 

    Welding's numbers are more specific than they first look: two wall/window tiers gated at Welding 2 and Welding 8, four leveling brackets with sourced XP-per-use rates, two occupations and three traits that shift starting level or XP rate, and five skill books that double up two levels each. None of it requires guesswork — the wiki's own tables and quoted lines cover the whole progression from a fresh Welder to a maxed-out metalworker, right down to which torch uses are worth spending first.
